Cel-Fi ROAM R41 Mobile Signal Booster – In-Vehicle 3G/4G/5G Coverage Solution

The Cel-Fi ROAM R41 is a premium in-vehicle mobile signal booster engineered for Australians who travel, work or explore beyond reliable mobile coverage.

Designed to improve 3G, 4G and 5G signal performance across all major Australian networks, the ROAM R41 enhances voice clarity, call stability and mobile data speeds inside your vehicle - even in remote or low-signal environments.

Built on Nextivity’s advanced IntelliBoost technology, the ROAM R41 continuously analyses the mobile network and intelligently boosts the strongest available signal in real time. Whether you’re touring the outback, working on regional job sites, towing a caravan, or operating a service vehicle, this unit delivers consistent, high-quality connectivity where it matters most.

Compact, easy to install and legal for use in Australia, the ROAM R41 includes a roof-mounted external antenna to capture weak signals and a low-profile internal antenna that rebroadcasts improved coverage throughout the cabin. From phone calls and messaging to navigation, streaming and remote work, the ROAM R41 helps keep you connected when distance or terrain would normally shut you off.
